In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

The droplet behavior of 83.9 wt.% HAN water solution was investigated experimentally with various ambient temperature and nitrogen environment. At the initial stage of evaporation under thermal decomposition temperature of HAN, gradual decreasing of droplet diameter was observed. After that, the droplet started to expand due to the internal pressure build up by water nucleation inside the droplet. The micro explosion was observed at higher temperature than the decomposition temperature of HAN and the remaining droplet showed similar behavior of single composition droplet. The decreasing rate was augmented as the ambient temperature increasing.

Deep vein thrombosis is recognized as a common complication in surgical patients in western countries especially in patients with high risk factors. The purposes of this study were to detect leg DVTs in early postoperative period by non-invasive surveillance and to analyze the risk factors of DVT. One hundred seventy one patients who underwent major operations(67 curative resection of colorectal cancer, 64 total hip replacement, 38 femur operation for fracture, and 2 colon resections for benign colon disease) were included for the prospective surveillance of leg DVT within 2 weeks after the operations. For the surveillance of leg DVT, strain gauge plethysmography(SPG) and Duplex scanning of both legs were completed for all patients except 10 patients. These 10 patients were examined in only one leg. The patients with past history of leg DVT or under prophylactic anticoagulant therapy were excluded from this study. To determine the risk factors related with leg DVT formation, age and sex of the patients, indication of surgery or surgical procedures, duration of operation, position during the operation, duration of postoperative immobilization, and preoperative serum level of antithrombin III (AT- III) were analyzed using Chi-square test. After performing SPG of 342 legs, 38 legs, showed abnormal on venous outflow/venous capacitance discriminant line chart, and 13 legs of 12 patients showed the finding(s) suggesting DVT on duplex scanning. Among the patients with abnormal duplex findings, 7 limbs(53.8%) were symptomatic, but the remaining 6 legs were silent. In 6 (15.8%) patients of 36 femur operations, 3(4.7%) of 64 total hip replacements and 3(4.5%) of 67 curative resections of colorectal cancer developed DVT by duplex scanning in the iliac(5), femoral-popliteal(6), and isolated calf(2) veins. After analyzing the risk factors, we could not find any statistically significant(p<0.05) factor related with leg DVT.

The purpose of this study is to evaluate the effect of width-thickness ratio (w/t ratio) on structure performance of concrete-filled Hollow Structural Section(HSS) bracing members. It has been found that bracing that experience more rapid strength deterioration and earlier fractures with increasing their w/t ratio. In order to reduce such poor behavior of bracing members having a large w/t ratio, concrete filled tubular bracing members can be used. This study investigated the effect of infilled concrete on bracing members having different w/t ratios. Experimental tests were carried out using quasi-static reversed cyclic loading with a symmetric compression and tension. Five full-scale test specimens were made. The test results showed that concrete filling delayed the occurrence of initial local buckling. Infilled concrete also changed the local buckling mode and reduced the severity of local buckling, thereby the occurrence of cracking and fracture in the concrete filled specimens were delayed. Furthermore, this study showed that infilled concrete is more influential to the specimens having a larger w/t ratio.

ISP의 BcN 투자 및 요금체계 평가모형 : 실물옵션과 몬테카를로 시뮬레이션의 응용

모든 정보통신서비스가 All-IP 통합 인프라로 제공되는 BcN 구축은 우리나라의 핵심 국책사업 중의 하나로, 인터넷 강국으로서의 글로벌 입지를 굳히는데 결정적인 역할을 할 것으로 기대된다. 그러나 BcN 기술의 성숙에도 불구하고, 제도적 측면에서 이의 성공을 뒷받침하는 연구는 드물다. 특히 BcN 요금체계와 같은 정책적 문제에 대해서는 별다른 진전이 없다. 본 연구에서는 요금정책이 BcN 투자에 미치는 영향을, 실물옵션과 Monte Carlo 시뮬레이션을 이용하여 분석하였다. 실험결과, BcN 수요의 불확실성뿐만 아니라, 요금체계와 관련된 정책대안이 사업자의 수익구조와 투자동기에 중요하게 작용하였다. 또한 수익과 투자시점은 밀접한 관계를 가지며, 트래픽 규모가 수입에 직접 반영되는 요금체계에서 BcN 투자가 앞당겨짐을 알수 있다. 특히 ISP와 CP간의 요금체계가 투자 의사결정에 보다 크게 작용하는 것으로 파악된다. 이러한 결과는, 사업자의 자발적인 첨단 인프라 및 서비스 개발이 국민경제에 긍정적으로 작용하는 동태적 효과를 보다 전향적으로 검토할 것을 요청한다.
한국인 Fragile-X 증후군 환자의 분자 유전학적 진단
김경모,유한욱 울산대학교 의과대학 1994 울산의대학술지 Vol.3 No.2
Fragile-X syndrome (FXS) is the most common cause of inherited mental retardation. Until recently, the diagnosis of FXS has been made based on the cytogenetic expression of the fragile site at Xq27.3 (FRAXA) in the patients' cultured cells and on the results of linkage analysis with DNA markers surrounding the fragile X locus. The recent cloning of fragile-X gene(FMR-1) made it possible investigate the molecular defects in FMR-1 gene of individuals at risk. Vast majority of molecular defects of FXS has been known to be an abnormally amplified trinucleotide(cytosine guanine guanine) repeat. This study aims at establishing the molecular genetic diagnosis of FXS as well as correlating genotype-phenotype analyzing the increment of amplified CGG repeat number, clinical findings, and cytogenetic expression rate in two Korean families with FXS patients. The FXS patients are tested cytogenetically & molecular genetically. The fragile site at Xq27.3 was cytogenetically expressed in folate deficient medium by culturing lymphocytes for 4 days. Molecular diagnostic approaches utilize the genomic DNA Southern blot analysis using genomic probe FXA 241 (ONCOR) and radiolabelled PCR-denaturing polyacrylamide gelelcetrophoresis. Each patient expressed a FRAXA site in folate deficient medium with the expression rate of 38%, 16% respectively. The molecular genetic study showed that each patient had the CGG amplification 1.6kb, 0.7-0.8kb in the FMR-1 gene respectively. In addition, this study clarified the carrier status of each family members. In conclusion, molecular genetic studies employed in this study can be utilized for a confimatory diagnostic purpose in FXS patients.
